Abstract
The invention relates to a valuable document, such as a banknote, identification card, or the like, comprising a first machine-verifiable, physical or chemical feature and comprising a second machine-verifiable, physical or chemical feature, whereby the first and second verifiable features can be machine-verified separately. The valuable document loses the first verifiable feature at a first temperature, and the valuable document loses the second verifiable feature at a second temperature which differs from the first temperature.
Description
The present invention relates to have two kinds and be applicable to checking vital document composition authenticity, mechanical testability matter, this purposes that is applicable to the composition of checking vital document authenticity has with the method for the vital document of the authentication feature of two kinds of verifiable physical propertys of machinery and this vital document of manufacturing and checks the material of carbonization or the method for the authenticity of ash content.
Vital document of the present invention can be to need false proof any file.Especially, these files comprise banknote, scrip certificate, documentary evidence and identity card, chip card etc.These vital documents are based on cellulose or cotton material or make based on plastics or these mixtures of material.
In order to prevent the vital document forgery, must make vital document have the authentication feature that can not be forged, perhaps if will forge and under the situation of disproportionate high cost, to carry out.For example can use fluorescent material, magnetic particle and based on the detectable material of its specific physical property as authentication feature.The verifiable authentication feature of term machinery is meant the feature that can test by machinery especially, and the feature of testing with the people is different, and is especially visual.The printed image that described people's verification characteristics comprises for example watermark, knob rope decorations, produced by photolithographic process or additive method.For example, magnetic material is highly suitable for the machinery check.Magnetic material can adopt the form of magnetic, is added in the vital document in manufacture process.Such magnetic can be a hard magnetic, and promptly they magnetize the back and produce permanent magnetic field, also can be soft magnetisms, and promptly they only magnetize under the external world excites the influence in magnetic field.
Yet, according to the statement of prior art, known can use luminescent marking as the verifiable authentication feature of machinery, various ways is arranged.Make between fluorescent material and the phosphorus and produce difference, fluorescent material under the condition of exciting irradiation, the ray of an emission characteristic, and phosphorus for a long time can also divergent-ray after closing exciting irradiation.Use the proof of the heterogeneity of luminescent substance as authenticity, for example, the duration of the observability of excitation spectrum and emission spectrum, emission and invisibility, any afterglow or its half-life and emission band width narrow and wide.Can improve false proof reliability in addition by many such analytical standards, because the adulterator does not understand the character of being analyzed, so he has to copy.
What often use is the luminescent substance of only launching in very narrow wave-length coverage, for example rare-earth compound.They have the advantage of the wide wavelength luminescent substance of emission, and therefore its emission spectrum, thinks that this class material is used for its authenticity of machinery checking and has higher security value than the more characterization of other materials.For the security that improves emission broadband material is worth, described according to for example DE3020652, their emission spectrum changes in distinctive mode.
For crime, if the characteristic material is used for the safety of file even is burnouted at file, it is useful still needing authenticating document, is actually from real file without the combustion residue of identification confirming.From another point of view, characteristic material in the vital document ash content that is contained in burning is reclaimed and be used for imitated counterfeit become impossible.
Thus, the objective of the invention is to propose a solution, this scheme can clearly be identified vital document, and it is based on vital document itself and ash content thereof, but the authentication feature that do not allow illegally to regenerate is with imitated vital document.
The present invention is based on following discovery, that is, can test independently of one another and variation or the different physics of disappearance or the purpose that chemical property realizes this contradiction under different temperatures by providing.Therefore, as what invented, vital document is characterised in that to have two kinds of verifiable physics of machinery or chemical property at least, these character can be tested independently of one another, therefore, vital document loses at least a mechanical testability matter under first temperature, and obviously is being different under second temperature of first temperature, might lose the verifiable character of another one.
Preferred version is, verifiable character is positioned at same position and/or based on identical physics or chemical phenomenon.When these character comprised not character based on same physical phenomenon, they can be down to the disappear heterogeneity of the single characteristic material that maybe can measure variation of small part in different temperatures.Preferably, can use two kinds of characteristic materials, this material respectively shows one of testability matter.
According to the solution of the present invention, a kind of vital document is provided, as banknote, identity card, its
Have at least two kinds of luminescent substances,
Check the luminosity of luminescent substance independently of one another by machinery, thereby
Under first temperature, first luminescent substance forfeiture luminescent properties and
Under second temperature, second kind of luminescent substance forfeiture luminosity;
It is characterized in that described first and/or second temperature is higher than the specific ignition temperature of vital document.
According to such scheme of the present invention, first temperature is less than or equal to the specific ignition temperature of vital document, and second temperature is higher than the specific ignition temperature of vital document.
According to such scheme of the present invention, first and/or second temperature is higher than the specific ignition temperature of vital document, but is lower than the incineration temperature.
Such scheme second temperature according to the present invention is higher than the incineration temperature of vital document.
The described vital document of such scheme according to the present invention, the first and second characteristic materials are respectively the inorganic light-emitting material.
The described vital document of such scheme according to the present invention checks at least a in the luminosity of luminescent substance to be included in the safe bar or in the safety fibre independently of one another by machinery.
The described vital document of such scheme according to the present invention, at least a in the luminosity are contained in the base substance of vital document.

The check physical property,
According to the temperature that vital document suffered stored reference value is proposed,
Reference value and measured value are compared.
In addition, in selecting testability matter, should consider that selected two temperatures scope is relevant with the burning of vital document by the present invention.It at first is specific ignition temperature, be that vital document is in the temperature of burning under air conditions under this temperature, the banknote of lighting with lighter with cigarette for example, next is a common temperature, vital document burns in the high-temperature incinerator of this temperature, because its pollution or destructiveness, when making them no longer be suitable for circulating,, destroy in high-temperature incinerator by means of oxygen or other materials by the publisher.General incineration temperature be positioned at about 1000 ℃ or more than.Specific ignition temperature preferably between 400 ℃-600 ℃, is preferably 500 ℃.
Because the burning of vital document is carried out in a large number, so in any case according to the present invention must guarantee unauthorized people can not be from the combustion residue of the vital document of the burning of the vital document that might forge recovery authenticity sign.
Thus, the testability matter (E that uses by the present invention
1, E
2Deng) must reach a kind of in the following condition, wherein, T
1Refer to specific ignition temperature, T
2Refer to incineration temperature:
First possibility:
Be lower than T
1The time, vital document is lost the first character E
1, and at T
1And T
2When above, retention properties E
2
In this composition, according to the testability matter E of temperature stabilization
2, can prove that ash content is from real vital document.Yet with regard to the essence of burning, burning or burning can not get conclusion under conditions of air.
Second possibility:
Be higher than temperature T
1The time, vital document retention properties E
1And E
2, and be lower than temperature T
2The time, forfeiture character E
1, be higher than T
2The time, retention properties E
2
In this case, based on character E
2, not only determine ash content from real vital document, but also determine the mode of vital document burning, if because ash content still shows two kinds of character E
1And E
2, then vital document burns under air conditions, if ash content only shows character E
2, then vital document has passed through the processing of incineration temperature at least.
The 3rd possibility:
When being lower than T
1The time, vital document is lost its character E
1, and when being lower than T
2The time, forfeiture character E

2, then this point can be used as the proof of burning under air conditions.
The 4th possibility:
When being higher than T
1The time, vital document retention properties E
1And E
2, and be lower than T
2The time, then lose its two kinds of character.
In addition, might prove the burning under air conditions, so that as previously mentioned, discerning occurrent burning file is real vital document, and under certain conditions, can change int file into.If ash content neither shows character E
1, do not show character E yet
2, in this case, whether be original real just may can not get conclusion with regard to vital document.
The purpose that proposes with regard to the present invention, can the scope of application effect widely, as luminous, magnetism, conductance or chemical reaction.With regard to the present invention, an important aspect is to estimate at least two kinds of physics or chemical property, and when being higher than certain first temperature, one of them is reversible variation or disappearance at least, and when being higher than first temperature, keeps the second quality.
According to optimum implementation of the present invention, vital document has two kinds of luminescent substances of its luminosity of forfeiture under different temperatures.Organic and the composition inorganic light-emitting material is specially suitable, because organic luminescent substance is just lost its luminosity at low temperatures already, and many inorganic light-emitting materials are temperature stabilizations.
The organic luminescent substance of potentially unstable comprises various dyestuff, as methylenum careuleum, rhodamine (rodanmine), anthracene, quinazolone, benzozazine or analog, rare earth chelate compound or rare earth acetonate.By the operable inorganic stabilized illumination material of the present invention is rear-earth-doped host matrix.Can use artificial schellite, granatic acid (granate) yttrium, yttrium vanadate, oxidation of sulfureted (oxisulphide) yttrium or its analog is preferred as host matrix.Concerning sightless code, the wavelength of its emission is in infrared scope, and preferred host matrix contains the material that is selected from chromium and iron, and rare earth element is selected from neodymium, ytterbium, praseodymium, erbium or holmium.The compound that use contains rare earth element is preferred, because their emission band is very narrow, therefore is fit to very much the machinery check.
Yet, replace unsettled organic luminescent substance, the zinc sulphide that can also use inorganic unstable luminescent substance to mix as silver-or copper/cerium.
According to another optimum implementation of the present invention, both can also use under certain temperature the different magnetic materials that can irreversible change also can completely lose its magnetic behavior.Iron oxide (Fe
3O
4), black chromium oxide and barium ferrite be the example with magnetic material of medium hard temperature stabilization to hard magnetic.
On the contrary, what the temperature stability difference was a little is metallicl magnetic material, as Powdered or laminar iron or cobalt.They show that soft magnetism is to hard magnetic.Cobalt-iron or nickel-ferro alloy also be soft magnetism and be easy to the burning.The other example of ultrahard magnetic and the material that is easy to burn is cobalt samarium (SmCo
5).
Even at low temperatures, the magnetic material that is easy to burn completely loses its magnetic or changes its magnetic property in the mode of very characterization.On the contrary, the magnetic of the magnetic material of temperature stabilization keeps constant.
If vital document is the paper series that regulation has different count values, as has a banknote of different denominations, various denominations are provided have different performance to being favourable, so that when checking combustion residue, might determine not only whether file is " real " or " forgery ", and can also determine concrete grade, the denomination of vital document for example.This point is practical especially under the condition of banknote, because the denomination of banknote often can not determine from the residue of burning, comes from specific banknote yet the owner wishes to confirm ash content.
Adding the characteristic material can realize by different modes.If vital document is made up of paper, perhaps comprise one deck paper, then in the process of papermaking, the characteristic material is sneaked in the paper pulp equably, or spray, print or be applied in the specific region, perhaps be incorporated in the paper web final, that be still humidity.
If vital document comprises plastics, then the characteristic material also can add in the plastic material and with plastics in the plastics-production process and is processed into film or fiber.These films or fiber can be used as vital document or are used to make vital document.Can also in paper-making process, be cut into for example strip, film be imbedded paper spare as the safety bar.Also might be added to the characteristic material in security fiber or the coin.In addition, when using, also can introduce the characteristic material material itself of security fiber or coin or be imprinted on the surface and upward or in dye bath dye together with dyestuff as the security bar.
Another possibility comprises the coverlay use of plastic film being made identity card or passport.
In addition, vital document can also print with the printing-ink that contains characteristic material (multiple).Yet the characteristic material also can be contained in different printing-inks.Any printing process can be used, especially photolithographic process, heat transfer printing, add heat embossing or screen printing.
The following examples are used to briefly explain the scope of possibility.
Embodiment 1
